UNITED STATES EDWARD T. DYSON, OF OAKLAND, CALIFORNIA.

LUG BOX.

Application filed December 27, 1923. Serial No. 682,941.

T 0 all whom it may concern Be it known that I, EDWARD T. DYsoN, a citizen of the United States, residing at Gakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Lug Boxes, of which the following is a specification.

My invention is an improved packing box.

The object of my invention is to provide a box which is constructed out of inexpensive material, and which is very rigid and strong when assembled.

Another object of my invention is to provide a paper box with wooden reinforcing strips, these strips to interlock at the corners to form a rigid structure.

In the drawing in wh'ch my illustrated Figure 1 is a plan view of my box in un folded position.

Figure 2 is a sectional view taken on the line 22 of Figure 1.

Figure 3 is an end view of my box as assembled.

Figure 4 is a sectional view taken on the line 44 of Figure 3.

Figure 5 is a plan view, with the cover raised, of a modified form of my invention.

Figure 6 is a sectional view taken on the line 66 of Figure 5.

Referring more particularly to the drawing, my box is composed of a heavy paper strip 1 which is creased at 2, 3, 4 and 5 to form a front side 6, a bottom 7, a rear side 8 and a top 9. The sides 10 and 11 are seinvention is cured to the bottom 7 by strips 12 and 13,

respectively, and are adapted to fold inwardly, as shown in Fig. 1, thus forming a flat sheet for shipment. Locking cleats 14 and 15 are secured to the upper edges of the sides 10 and 11 respectively.

Reinforcement bars 16 and 17 are secured to the outer edges of the front 6, and bars 18 and 19 to the rear 8. The ends of the bars 16, 17 18 and 19 are beveled, and are adapted to fit into notches 20 and 21 in the strips 12 and 13 respectively. The cleats 14 and 15 have notches 22 and 23 respectively into which the bars 16, 17, 18 and 19 fit, thus binding the edges of the box securely together and prevent warping of the box when packed.

Slats 24 and 25 are secured to the bottom 7; a slot 26 is secured to the front wall 6 adjacent its upper edge and is adapted to be bent over on the top 9, as shown in Figure 3, to hold the forward edge of said top securely in place. A slat 27 is secured to the rear edge of the top 9. Nhen the box is filled, nails are driven through the slat 26 and cleats 14 and 15 into the bars 17 and 16,

through the slat 27 and cleats 14 and 15 into the bars 18 and 19, through the slats 24 and 25 and cleats 12 and 13 into the bars 16, 17, 18 and 19; the box is thus securely held together.

It is not necessary to nail the box until after it has been packed and is ready to ship, the notches in the cleats 12 and 13 being sufficient to hold it together.

In the modified form shown in Figures 5 and 6, the structure of the box is identical to that just described, with the addition of vertical blocks 30 and 31 secured to the front face 6 and rear face 8 respectively, and a flap 32 secured to the upper edge of the face 6 and projecting inwardly. This structure is only on long boxes and those in which heavy articles are packed such as cans of fruit or vegetables. The blocks afford an additional reinforcement between the top and the bottom, so that the center of the box will not sag or break through. When the box is nailed, nails are driven through the slats 24, 25, 26 and 27 into the blocks 30 and 31.

Having described my invention, I claim:

1. A packing box comprising a strip of thin material adapted to form the top, front, rear and bottom faces, side strips secured to the bottom of said box, strips secured to the outer edge of the bottom, reinforcing bars secured to the outer edges of the front and rear sides, locking cleats secured to the upper edges of said ends, said locking cleats and strips having notches formed therein into which said reinforcing bars are adapted to fit.

2. A packing box comprising a strip of thin material adapted to form the top, front, rear and bottom faces, side strips secured to the bottom of said box, reinforcing bars secured at the edges of the box, a plurality of vertical blocks secured to said front and rear faces and positioned between the sides, and an inwardly projecting flap secured to said front face.

In testimony whereof I affix my signature.

EDWARD T. DYSON.
